Impact of Environmental Constraints in the Steel Industry

Abstract

Based on Japanese data, the environmental management problem in the iron and steel industry has been investigated from various points of view. Some qualitative characteristics of the pollution problems in this industry are overviewed and classified by comparing them with pollution problems in other industries. To make the quantitative investigation of pollution phenomena in the iron and steel industry, a model plant is introduced with modern pollution control devices. To prevent the shortage of natural resources and to soften the environmental constraints in the future, the need for recycling systems for the wasted iron and steel is emphasized from the total system's point of view.
